/**
 * Applies configured decision for URIs with content length greater than
 * a given threshold length value. Examines either HTTP header Content-Length
 * or actual downloaded content length (based on the useHeaderLength property), 
 * and has no effect on resources shorter than or equal to the given threshold 
 * value.
 * 
 * Note that because neither the Content-Length header nor the actual size are
 * available at URI-scoping time, this rule is unusable in crawl scopes. 
 * Instead, the earliest it can be used is as a mid-fetch rule (in FetchHTTP), 
 * when the headers are available but not yet the body. It can also be used 
 * to affect processing after the URI is fully fetched.
